                           MethodResult methodCallFailureResult)

Description copied from class: BaseMethod

Calls the declared method on the given component with the provided method call arguments.

Overrides:

invoke in class BaseMethod<ActivatorParameter,java.lang.Object>

Parameters:

componentInstance - The component instance on which to call the method

rawParameter - The parameter container providing the actual parameters to provide to the called method

methodCallFailureResult - The result to return from this method if calling the method resulted in an exception.

Returns:

true if the method was called successfully or the method was not found and was not required. false if the method was not found but required. methodCallFailureResult is returned if the method was found and called, but the method threw an exception.
